A healthy fall Butternut Squash pasta
Butternut squash is one of my favorite fall ingredients because it is so versatile. It is great roasted on its own, but I like it best blended into sauces and soups.
I decided to roast the squash with tomatoes, onions and simple seasonings to give the sauce a deeper flavor. Once roasted, the veggies are blended with pasta water to make a creamy smooth sauce.

Why use frozen butternut squash instead of fresh?
The only reason I use the frozen butternut squash is because it makes things way easier and saves time! I hate to peel, deseed, and chop fresh butternut squash.
I find it difficult and time consuming. Plus, frozen butternut squash is normally very affordable. It is most commonly available in the freezer section during the fall so I usually stock up on a few bags that I can use throughout the year.
If you prefer to use fresh butternut squash, that will work just fine! Follow the same steps as you would with the frozen squash.
Let’s make some Butternut Squash Pasta Sauce!
Step 1: Roast veggies in the oven
To begin, preheat oven to 450F and line a baking sheet with parchment paper. Then, place frozen cubed butternut squash, chopped tomatoes and sliced onion on the baking sheet.
Next, drizzle olive oil on top and season with salt, pepper, and thyme. Then, mix to cover the vegetables evenly with oil and seasonings.
Bake at 450F for 20 minutes.
Step 2: Cook pasta and reserve pasta water
Then, while the veggies bake, cook the pasta according to package instructions. Before you drain the cooked pasta reserve 1/3 cup of the pasta water and place in a blender.
Step 3: Blend sauce and mix with pasta
Next, take the cooked veggies hot from the oven and blend with the pasta water until a smooth sauce remains.
Finally, pour the sauce over the cooked pasta and toss to coat. Serve immediately with parmesan cheese or plant based parm alternative.
Step 4: Enjoy!
How long will this plant based butternut squash pasta keep in the fridge?
I recommend storing the cooked pasta and sauce separately for meal prep. You can keep the cooked sauce in the fridge for up to 7 days. If you are eating some of the pasta immediately, you can toss some of the pasta in the sauce while its hot and store the rest separately.

Jan says
What kind of tomatoes do you use ? Roma ? or canned ? Please advise, I want to make this soon ! YUM
Madeline says
I used grape tomatoes but you could also use Roma or any other type of fresh tomatoes. I would recommend fresh over canned for this recipe.
Lenaya says
Can I use fresh uncooked butternut squash?
Madeline says
Yes, just peel, deseed, and chop fresh butternut squash and then follow the rest of the instructions.
Flo says
Delicious. Added a touch of sage and it really added a little something special to it.
Madeline says
That is a great addition. Thanks, Flo!

I’ve not made this yet but will add sage too. Butternut squash and sage are a match made in heaven 😀
Madeline says
YES, love that combo!

Can I make this without the tomatoes? My son is allergic and was wondering if there’s an alternative for it.
Madeline says
Hi there! You could eliminate or try red bell pepper.

What is the name of this pasta shape? I can’t find it anywhere.
Thank you!

Could you make this with fresh butternut squash??

Yes! If you prefer to use fresh butternut squash, that will work just fine! Follow the same steps as you would with the frozen squash.
Connie Ginther says
Made this tonight and it was good. I added chicken and used chickpea pasta.
Madeline says
Yay! Sounds delicious, Connie!
Lindsey says
Great recipe! I didn’t have a yellow onion, so I used a (eyewatering) red. I eyeballed the spices and added some all spice, rosemary, 2 tbsp ground flax, and 2 tbsp hemp in the blending phase. The flax/hemp gives it a more meaty texture. Used soymilk instead of water. Had to play with the salt and it felt like something was missing initially once I combined everything into the pan to reheat it, so added slightly more and added parmesan, which really brough everything together.
I think my actual ratios were 20 oz bags of butternut squash and one can of diced tomatos.
Breanna says
Incredible. I have a ton of squash from the garden and I now know how I will be consuming it.
Madeline says
AWESOME! So glad to hear it, Breanna!
Haley says
We had this for dinner tonight and it was SO good. Really creamy and flavorful, and we love that it was made from such simple, healthy ingredients!
Madeline says
Awesome!! Thanks, Haley!
Annemarie says
If you want to roast a fresh butternut squash, just cut it in half and remove seeds, roast it, and then purée the whole thing with the skin! (I remove blossom and stem ends.) Seriously a game changer!
Madeline says
Great tip! Thanks, Annemarie!
